Reference designs

36~57-Vdc input, 5-V/4-A output isolated flyback with synchronous rectification reference design

This reference design is a 36~57-Vdc input, 5-V/4-A output isolated flyback converter using LM5155 and UCC24612. The switching frequency is 250 kHz. With the synchronous rectification controller UCC24612 and a MOSFET at the secondary side, the system achieves 89.29% peak efficiency at 36-V input (...)
